I've designed many small projects that test the boundaries of this relatively new technology. In one exploration of texture I modelled separate textures on each face of a cube that could be built using a FDM machine. <img src="http://payload55.cargocollective.com/1/1/47177/3418956/IMAG0301 fixed.png" width="670" height="402" width_o="1280" height_o="768" src_o="http://payload55.cargocollective.com/1/1/47177/3418956/IMAG0301 fixed_o.png" data-mid="17595083" border="0" align="left"/> In another experiment I wanted to play with additive manufacturing at a scale and with materials that where not normally used. This effort culminated in building a cement garden stool with an organic form that could not be constructing using conventional cement forming such as casting. Using laser-cut templates to guide me, I applied layer after layer of quick curing cement with a pastry bag. I found that cement performed very well as a build material. It was able to accomodate some substantial overhangs without support material and had no problem bonding to the layer below. http://meisenholder.com/Konversation-Kaleidor http://meisenholder.com/following/meisenholder.com/Konversation-Kaleidor Mon, 14 May 2012 22:02:05 +0000 The Portfolio of David Meisenholder 3403323 The Konversation Kaleidor is a large, suspended kaleidoscope. Two people can stand on opposite ends and talk through a mirrored triangular space.

Inevitably our sleeping pads drift apart in the night and if I want to keep spooning I'll find myself on the cold ground or trying to eek out some real estate on my girlfriend's pad. The Cuddle Pad is a modular sleeping pad system that allows you to interlock multiple sleeping pads so you can snuggle with your partner all through the night.

When confronted with the challenge of keeping these babies alive, I had to do in-depth research into neo-natal health and the cultural customs of India. After many Skype interviews with Indian health professionals, I found that during ambulance transport EMTs were usually busy stabilizing the mother, so the new borns were left in the hands of a relative. The Stork is a neonatal transport unit designed for these interim caregivers. <img src="http://payload17.cargocollective.com/1/1/47177/2656052/WP_001235 copy.jpg" width="670" height="502" width_o="2048" height_o="1536" src_o="http://payload17.cargocollective.com/1/1/47177/2656052/WP_001235 copy_o.jpg" data-mid="17497404" border="0" align="left"/><img src="http://payload17.cargocollective.com/1/1/47177/2656052/BabyAlive Research.jpg" width="670" height="502" width_o="2048" height_o="1536" src_o="http://payload17.cargocollective.com/1/1/47177/2656052/BabyAlive Research_o.jpg" data-mid="17496606" border="0" align="left"/><img src="http://payload17.cargocollective.com/1/1/47177/2656052/BabyAlive Brainstorm.png" width="670" height="550" width_o="1800" height_o="1478" src_o="http://payload17.cargocollective.com/1/1/47177/2656052/BabyAlive Brainstorm_o.png" data-mid="17496581" border="0" align="left"/><img src="http://payload17.cargocollective.com/1/1/47177/2656052/BabyAlive Closed.png" width="670" height="500" width_o="1800" height_o="1345" src_o="http://payload17.cargocollective.com/1/1/47177/2656052/BabyAlive Closed_o.png" data-mid="17496593" border="0" align="left"/><img src="http://payload17.cargocollective.com/1/1/47177/2656052/Baby alive open.jpg" width="670" height="502" width_o="2048" height_o="1536" src_o="http://payload17.cargocollective.com/1/1/47177/2656052/Baby alive open_o.jpg" data-mid="17496381" border="0" align="left"/><img src="http://payload17.cargocollective.com/1/1/47177/2656052/BabyAlive openOpen.jpg" width="670" height="502" width_o="2048" height_o="1536" src_o="http://payload17.cargocollective.com/1/1/47177/2656052/BabyAlive openOpen_o.jpg" data-mid="17496599" border="0" align="left"/> Experts at the Packard Children's Hospital were able to direct me toward many easy ways to identify common problems and foolproof remedies. The Stork has a simple checklist on the front to diagnose the newborn's condition. If there is any sign of a problem the caregiver can open a flap to find tools and more in-depth instructions on how to treat the child. The Stork prototype is currently being tested in India by D-Rev. http://meisenholder.com/Duo-Flush http://meisenholder.com/following/meisenholder.com/Duo-Flush Sun, 22 Jan 2012 17:50:44 +0000 The Portfolio of David Meisenholder 2652504 The Duo Flush is a system to retrofit an normal toilet to have dual-flush capability and save water.

D2M was hired to make them a reality. The GL20 glasses can take pictures and video and display them on two small OLEDs and run for up to 6 hours. Fitting the electronics to accomplish this in a package designed to fit comfortably on the face was not a trivial challenge. <img src="http://payload17.cargocollective.com/1/1/47177/2651925/d4d66070c0d5fbf16b2bc8786ca9a092.jpg" width="670" height="377" width_o="970" height_o="546" src_o="http://payload17.cargocollective.com/1/1/47177/2651925/d4d66070c0d5fbf16b2bc8786ca9a092_o.jpg" data-mid="13428044" border="0" align="left"/><img src="http://payload17.cargocollective.com/1/1/47177/2651925/whiter2.jpg" width="670" height="380" width_o="712" height_o="404" src_o="http://payload17.cargocollective.com/1/1/47177/2651925/whiter2_o.jpg" data-mid="13430280" border="0" align="left"/><img src="http://payload17.cargocollective.com/1/1/47177/2651925/hinge2.jpg" width="670" height="486" width_o="685" height_o="497" src_o="http://payload17.cargocollective.com/1/1/47177/2651925/hinge2_o.jpg" data-mid="13430305" border="0" align="left"/><img src="http://payload17.cargocollective.com/1/1/47177/2651925/Arm3.jpg" width="573" height="458" width_o="573" height_o="458" src_o="http://payload17.cargocollective.com/1/1/47177/2651925/Arm3_o.jpg" data-mid="13430015" border="0" align="left"/> I designed the arms and UI buttons for the GL-20. The turning point was when I designed a compound hinge that flex circuits could pass through. With this break through electronics could be distributed in the arms shrinking the overall package and making the glasses more balanced. http://meisenholder.com/Convert-Table http://meisenholder.com/following/meisenholder.com/Convert-Table Wed, 25 Aug 2010 19:07:06 +0000 The Portfolio of David Meisenholder 591066 I had just moved into my first apartment and found there was need for a coffee table that was more flexible than the standard static coffee table. Convert-Table is my solution. The table can take three forms depending where its users are sitting. If people are surrounding the table and interacting, Convert-Table can take the shape of a standard coffee table. However, I had two perpendicular couches and the residents would normally plop down on these. If this is the case, a hinged quarter can fold up and the table can take a shape that serves both couches. If only one couch is being used, another quarter can be folded up and the table converted into its long configuration that can span the whole length of one couch. As my first solo project, Convert-Table stood as proof that I could create to fulfill a need that existing product did not. . <img src="http://payload.cargocollective.com/1/1/47177/591066/101_1820.JPG" width="670" height="502" width_o="2048" height_o="1536" src_o="http://payload.cargocollective.com/1/1/47177/591066/101_1820_o.JPG" data-mid="2723089" border="0" align="left"/><img src="http://payload.cargocollective.com/1/1/47177/591066/101_1826.JPG" width="670" height="502" width_o="2048" height_o="1536" src_o="http://payload.cargocollective.com/1/1/47177/591066/101_1826_o.JPG" data-mid="2723112" border="0" align="left"/><img src="http://payload.cargocollective.com/1/1/47177/591066/101_1824.JPG" width="670" height="502" width_o="2048" height_o="1536" src_o="http://payload.cargocollective.com/1/1/47177/591066/101_1824_o.JPG" data-mid="2723220" border="0" align="left"/><img src="http://payload.cargocollective.com/1/1/47177/591066/scan0005.jpg" width="670" height="970" width_o="1417" height_o="2052" src_o="http://payload.cargocollective.com/1/1/47177/591066/scan0005_o.jpg" data-mid="2723261" border="0" align="left"/> http://meisenholder.com/Embryo http://meisenholder.com/following/meisenholder.com/Embryo Sat, 21 Aug 2010 22:17:48 +0000 The Portfolio of David Meisenholder 583479 Embryo is a dynamic stereo cabinet created with guidance from Ilan Dei Studio.

The mechanism used was reverse engineered and then enhanced to create Embryo. The contoured design was sculpted in Rhino and created using a CNC mill. The piece is totally automated using a motor hidden in the base and limit switches. The user can decide to use it in a manual mode where is is activated by the hidden switch or in an automatic mode where the user is recognized standing in front of it by a sonar range detector. A Parallax microprocessor will interpret the sonar signals and open the door when it determines the user was not simply passing by.

The goal of this project was to maximize the efficiency of solar cells through concentrating sunlight and high accuracy sun tracking. After working in the field installing and testing these trackers, I saw improvements that could be made to the tracker system. Ultimately, I designed and modeled a modification to tracker that would allow for more uniform alignment of solar modules and greater ease of installation. <img src="http://payload.cargocollective.com/1/1/47177/573644/High-Concentration_P_34019a.jpg" width="640" height="427" width_o="640" height_o="427" src_o="http://payload.cargocollective.com/1/1/47177/573644/High-Concentration_P_34019a_o.jpg" data-mid="2684610" border="0" align="left"/> At Boeing I was also given the opportunity to design structural components for satellites. These elements had to be very light and react to extreme vibrational loads well due to the fact that part of a satellite's life is spent strapped to a rocket. Designing for the harsh environments encountered by a satellite was very exciting especially for a space enthusiast like myself. <img src="http://payload.cargocollective.com/1/1/47177/573644/0_Sat_Launcher_1KR_H.jpg" width="670" height="502" width_o="2048" height_o="1536" src_o="http://payload.cargocollective.com/1/1/47177/573644/0_Sat_Launcher_1KR_H_o.jpg" data-mid="2684691" border="0" align="left"/> http://meisenholder.com/RangeBa http://meisenholder.com/following/meisenholder.com/RangeBa Mon, 16 Aug 2010 23:20:20 +0000 The Portfolio of David Meisenholder 572960 The RangeBa is an automated golf-ball collector designed to maintain a driving range.

The robot travels randomly on the range while scooping up balls with its rotating paddle and letting them fall into its storage basin. A weight sensor in the basin is triggered when 50 balls are collected and the Rangeba receives the signal to go home. The Rangeba is made entirely of clear acrylic to allow its IR sensor to find its base and head in the correct direction. When the unit reaches home a solenoid releases a trap-door and the collected balls are released at the home base. With a sense of accomplishment the RangeBa bravely returns to the range to find more balls. Untitled from D Meis on Vimeo.
